How to Convert 17 kilometers Into Miles?

Kilometer (km)

The kilometer, from the Greek khilioí (“thousand”) + the Latin metrum (“measure”), was introduced in France in 1799 as part of the new metric system. It’s defined as exactly 1,000 meters—or one ten-thousandth of the distance from the North Pole to the Equator.

• Exact length: 1,000 m
• Equivalent: ≈ 0.621371 mi
• Common uses: Road signage (most of the world’s highways), athletic events (5 km, 10 km races), and scientific measurement (e.g., topographic maps).
• Fun fact: The world’s longest road is the Pan-American Highway at over 48,000 km!

Mile (mi)

The mile has its roots in the Roman mille passus (“thousand paces”), each pace being two steps. In 1593, England standardized the statute mile at exactly 5,280 feet (1,609.344 m). Today, it remains the primary unit for road distances in the U.S. and the U.K.

• Exact length: 1,609.344 m
• Equivalent: ≈ 1.609344 km
• Common uses: Highway speed/mileage (e.g., “Drive 60 mi/h”), aviation & nautical miles (1 nautical mile = 1.852 km), and occasional sporting races (e.g., 1 mi track events).
• Fun fact: The fastest recorded mile run is 3 min 43.13 s by Hicham El Guerrouj in 1999.
